Jeopardy categories that could bring down Watson.

Despite blowing a Final Jeopardy! question about airports, IBM's computer dismantled its human rivals during Tuesday night's special edition of the "Jeopardy!" game show. Watson finished the first game of a two-game match with $35,734 in winnings, far ahead of runner-up Brad Rutter, who earned $10,400 and Ken Jennings with $4,800. The computer nailed answers on an impressive variety of topics, ranging from architecture to biological science to classical music to "Saturday Night Live." Still, it doesn't know crap about boobs. And here's an even bigger challenge for Watson. (Comic by Joel Watson at Hijinks Ensue)
